Prepared bitumen emulsion

In the preparation of bitumen emulsion of small amounts of a chemical compound to facilitate cell formation bitumen and it is added to the permanent suspension called emulsification in the preparation of each emulsion principle should be used, otherwise upon termination of affairs emulsification immediately contiguous cells and form a continuous phase and hence the formation of a continuous phase of emulsification.However, in the presence of a thin film of chemical composition as emulsifier mixture is added to the cells is called bitumen, the thin film acts as a protective coating and prevents the cells from joining. Emulsification can be divided into four categories, the first and second are of greatest importance.

1. anionic emulsifier instruments
2. cationic emulsion instruments
3. Non-ionic emulsion instruments
4. emulsion colloidal structures
4-1 anionic emulsifier instruments:
These emulsions are usually alkaline salt of an organic acid which are produced in an aqueous solution of metal cations and anions that its organic structure.
In that same time repulsive force is created between them to prevent the coalescence of bitumen cells.
4-2 cationic emulsion instruments:
These belts are organic substances that when the ions are molecules that carry a positive charge that is part of a long chain aliphatic organic materials which are soluble in the bitumen long chain aliphatic amine salts, quaternary ammonium and interesting examples emulsions such instruments are not compatible with each other. It cationic emulsions direction, if they are mixed positive and negative charges cancel each other ph and anionic emulsions Mygrdd.amvlsyvnhay clot clot usually alkaline and PH about 9 or higher If there is less than 6 cationic emulsions.
